Engineers use dust and starch to create concrete for building on Mars.

For its production, it will be possible to use materials available on the Red Planet: potato starch, magnesium salt and Martian dust. The new StarCrete concrete is twice as strong as conventional concrete, with a compressive strength of 72 megapascals. On Earth, it is impossible to build from such concrete - it will collapse due to moisture, but it does not rain on Mars.
